This is a REVISIT of Part 2 of the faulty Mega Drive consoles from eBay. This one doesn't display on the TV. There is a suspected short on one of the traces, will I be able to find it?
Hope you enjoy!

The magic things I use to break stuff;
My soldering iron: amzn.to/2Isf360
My leaded solder: amzn.to/3giGtI1
My flux: amzn.to/3lTrPIh
My soldering wick: amzn.to/3groIGn
My microscope: amzn.to/2VP3msU
My blue mat: amzn.to/3mUiIZl
My tweezers: amzn.to/2VOMjYc
My multimeter: amzn.to/2LjBgnN
My oscilloscope: amzn.to/3oPQQpU
My underpants: amzn.to/3gknvjY
PS. I'm not an expert in repairs at all. I do this for fun, and it may not be the best or safest way to go about repairing broken stuff. I'm pretty good at melting plastic though.

After worked in electronics for more than 20 years, NOTHING comes close to that feeling when you finally fix something that`s been a total pain in the ass :) well done bro.

I really feel like I went on a journey with you, this was a great watch! I actually laughed out loud when that sega logo popped up!

if their's one thing i love to see it's a 'f**king get in!' moment. those combined chips (315- series) fail in much the same way as CPU's and PPU's in SNES fail, repeated heat cycles and age eventually break down the internal connections of the chip, with the chip expected to do so much more than in earlier models its failure can throw up some very esoteric issues! often people harvest them in order to fix the much rarer Sega CDX unit as they're affected even more commonly.

The resultant "get in there!" was class, great result we are ready for the next instalment!!!

It's too bad I'm only seeing these a year later. I'd have been able to save you a bit of headache. All's well that ends well. Love the vids, my dude.

I appreciate your patience and your will to return to such a lengthy and difficult fix! I sure learned a lot from both those videos. Thank you.

Hi Steve, Congratulations on fixing this unit. It would help you to know a little more about AC theory. The Inductor is basically a coil of wire. The properties of an Inductor are, to pass DC and impead or try to block AC current flow. I believe your knowledge is mainly DC theory based and that's why you don't really understand the purpose of the inductor. This is common when learning electronics its often the first thing that's learned along with ohms law etc. It appears in this circuit that the Inductor and capacitor in parallel form a tuned circuit. Tuned circuits are intended to be used to pass or block certain frequencies, they have what's called resonance. This combination of inductor and capacitor could be referred to as a filter circuit. The Capacitor will block DC but pass AC so it has the opposite characteristics to the coil or inductor. To better understand, look at the impedance characteristics of an inductor and capacitor compared with frequency of an applied signal.The coil and capacitor are opposite to one another if you look at the characteristics. I hope this helps a little. Andy.
